TO ALL WHOM IT MAY CONCERN: L

Be it known that I, W. W. Mutants, of Portland, in the county ofGumberlaud,"and State of Maine, have invented a new and useful ImprovedTea-Pot; and I hereby declare the following to be a full, clear, andexact description thereof, which .will enable others to make and use myinvention, reference being to the. accompanying drawings, forming partof this specification, in whichp Figure 1 shows a top view of myimprovement, viz, a peculiarly-formed bottom-for a tea-pot. v Figure.2is a section of the same taken through the centre, and showing theformation of the bottom. f

The side, a, in fig. 2, represents the outside of the bottom, orthatpart which is-next to the stove or other article upon which the tea-potmay be placed. The side, 6, represents the insi de'of the .bottom of thetea p'ot Q I that is, when it is standipg or resting upon any article,it rests upon the projecting rim d c, which extends around the entirecircumference of the circular bottom.

It is well known that Britannia and other materials liable to melt fromheat cannot be safely employed in the manufacture'of this article,because of this liability to melt when placed upon any heatingnppuratus,and

also-that convenience requires that tea-pots, &c., should beso made asthat they may be, without injury, placed j upon a'heating-apparatus, inorder to keep. the contents hot. Earthenware, aless durable article, andone sub Y ject to fracture, is' on this account much employed.

The object of my invention is so to construct the bottom of a tea-potthat it can be safely employed to hold the articles usually placed in itwhile being heated, and this when the vessel is made of. materialsubject to the liability of melting by heat.

My improvement consists-in a peculiar formation of the plate or diskforming the bottom oi the tea-pot,

by which not the whole lower outside surface of the said bottom willrest upon. the stove or other heating- .apparatus, but only an edge,projecting slightly below the outer surface of the bottom, and raising;it somewhat from the stove, &c., is permitted to touch the surface fromwhich the heat is derived.

I obtain this projecting edge by bending the outeredge ofthe circularbottom downward, as seen in 1, and clearly illustrated in the section,fig, 2. d a show the edge upon which the tea-pot rests g on its bottom.Thus but a minute portion of the bottom comes in actual contact with aheated surface, While, between the residue offltbe bottom, a, and thestove, there is left a space sufficient to remove the liability ofmelting. l i

The body of the tea-pot is attached to such bottom in the ordinary way,which I do not claim; neither do I claim an improvement in theconstruction of Britannia pots, by making the lowerbody and bottomofsuch vessels of iron or metal, capable of bearing much greater heatthan Britannia, asseen in the patent of E. B. Manning, June 3, 1862,No.,35,4-57.

The nature of my invention is such that it does not require the bottomto be made of a metal. capable of sustaining a high degree of heatwithout melting, but the bottom may be made of tin, copper, or othermetal. By reason of the contact of only the downward-bcnt edge of thebottom, the durability of the pot largely increased, because thewholebottom surface is preserved from contact with anything upon whichthe pot may be placed. The body of the tea-pot is united with thisbottom by spinning up the lower part or bottom edge, so as to conform tothe inner sloping sides of-the raised part, 'thus leaving a shoulder onthe outside, and then soldering thc same, as common. The section isshowninl the drawing the wrong side up, as the teaspot rests on theedges d c, labeling the inside of the bottoun I am not aware of anybottom of this form resting on edges cl 0, and with this-method ofapplication.

What I claim as my invention, and desire to secure. by Letters Patent,is-

The improvement in the construction of potsliable to melt from theinfluence of heat, consisting of the bottom as herein shown, and appliedas illustratecl, for-the purposes set forth;
